1/8. Glomangioma in the nasal cavity and paranasal sinuses.The glomangioma is a hyperplastic lesion of the glomus body. This uncommon tumor is seldom located in the nasal cavity or paranasal sinuses. We present what is to our knowledge the eleventh documented case of an intranasal glomangioma. The differential diagnosis of this lesion, its symptoms, pathogenesis and therapy are discussed. Complete excision is normally curative for this tumor.- - - - - - - - - - ranking = 1keywords = glomangioma, glomus (Clic here for more details about this article) |
2/8. paraganglioma of the sphenoid sinus appearing as labile hypertension.Paragangliomas, also known as glomus tumors, are unusual, generally benign tumors most commonly found in association with major vessels and cranial nerves. Only a small number of these tumors have been described arising in the paranasal sinuses, and none of these has been physiologically active. The following case report describes a metabolically active paraganglioma arising in the sphenoid sinus.- - - - - - - - - - ranking = 0.00071607477498291keywords = glomus (Clic here for more details about this article) |
3/8. Glomangioma of the nasal cavity and paranasal sinuses.The glomangioma, a benign vascular tumour, derived from the cutaneous glomus bodies, should not be confused with paragangliomas, which are occasionally also referred to as glomus tumours. Up to now, only eleven cases of a glomangioma of the nasal cavity and the paranasal sinuses have been published. We report the case of a patient with a glomangioma of the ethmoidal aircell system. The tumour was completely removed under endoscopic-microscopic vision via endonasal access. A tumour recurrence was not observed over a period of eighteen months. The clinical signs, diagnosis, therapy and histological features will be discussed with reference to the literature.- - - - - - - - - - ranking = 1.5062918328649keywords = glomangioma, glomus tumour, glomus (Clic here for more details about this article) |
4/8. Intranasal glomangioma.Glomangiomas of the nasal cavity are a rare occurrence. Only 9 cases of this vascular tumor have been reported in the literature. A case of intranasal glomangioma is reported with a review of pertinent literature. The histogenesis, clinical presentation, diagnosis, immunohistochemical features, and treatment of these rare tumors are presented.- - - - - - - - - - ranking = 2.4982098130625keywords = glomangioma (Clic here for more details about this article) |
5/8. Nasal paraganglioma. A case report.Nasal paraganglioma. A case report. Nonchromaffin paragangliomas or chemodectomas arise in paraganglia distributed in various parts of the body. The jugular bulb, the vagal body and the bifurcation of the carotid artery are the most common sites of origin of paraganglioma in the head and neck region. Paragangliomas in the nose and paranasal sinuses are extremely rare and very few cases of definite paraganglioma arising primarily in the nose or paranasal sinuses have been reported. The paraganglioma is a slow-growing tumour that produces nasal obstruction, profuse epistaxis and facial swelling. Complete excision of the glomus tumour is normally curative. We report a case of nasal paraganglioma and discuss the diagnosis and therapy.- - - - - - - - - - ranking = 0.0066498702524332keywords = glomus tumour, glomus (Clic here for more details about this article) |
6/8. Intranasal pericytic tumors (glomus tumor and sinonasal hemangiopericytoma-like tumor): report of two cases with review of the literature.An intranasal glomus tumor and a sinonasal hemangiopericytoma-like tumor are reported. Both patients were elderly women suffering from nasal bleeding, and presented with a polypoid mass arising in the nasal septum. Microscopically, the glomus tumor displayed a proliferation of uniform rounded or cuboidal epithelioid cells arranged in sheets and interrupted by a rich vasculature with a characteristic configuration mimicking the normal glomus bodies, while the sinonasal hemangiopericytoma-like tumor featured a perivascular proliferation of spindle- to oval-shaped cells that were arranged in short fascicles. Both tumors shared immunohistochemical features supporting their myoid differentiation by the expression of vimentin, alpha-smooth muscle actin and muscle-specific actin, albeit with no immunoreaction to desmin. Both the intranasal glomus tumor and sinonasal hemangiopericytoma-like tumor are characterized by a perivascular growth pattern and myoid differentiation, having a close relation to the 'perivascular myomas', which was recently designated.- - - - - - - - - - ranking = 0.0057285981998633keywords = glomus (Clic here for more details about this article) |
7/8. Glomangioma of the nasal cavity. Case report and literature review.A case of glomangioma of the nasal cavity and the literature concerning this rare tumor are reported. Differential diagnosis, symptoms, pathogenesis and therapy are discussed. This uncommon benign neoplasm is seldom located in the upper respiratory tract. It originates from proliferating arteriovenous capillary anastomoses. Intranasal glomus tumors produce nasal obstruction, epistaxis and sharp pain. The treatment of choice is complete excision of the tumor. The prognosis is excellent when the glomangioma is completely removed.- - - - - - - - - - ranking = 1keywords = glomangioma, glomus (Clic here for more details about this article) |
8/8. Case report: glomus tumour of the nasal cavity and paranasal sinuses.Glomus tumours are relatively rare in the head and neck.
